Abstract

Extensible mast mechanism which is erected from a portable base (35) having a plurality of tape reels (39, 41, 43) mounted thereon. The tape reels are angularly oriented on the base with respect to a common, vertical axis, and each of the tape reels is adapted to receive a resilient metal tape (45) having longitudinal edges for winding and unwinding the tape. A plurality of guide rollers (151) on the base receive the respective longitudinal edges of the metal tapes and orient the tapes whereby the tapes are fed upwardly in plane parallel to the vertical axis and at an angle to each other to form a rigid structure. A geared winding mechanism (165) is located above the guide rollers and includes a plurality of rotatable windings which rotate about the vertical axis and wrap material about the rigid structure to reinforce the structure as it is being erected.
